AI for ready mix concrete producers, tested on tickets you already billed.

The buyer's order outranks the standard. ASTM C94, the Standard Specification for Ready-Mixed Concrete, defines its two sides plainly: the producer manufactures and the purchaser buys. Where the purchaser's requirements differ from the standard, the purchaser's govern. Its abstract also has cement, aggregate and admixtures measured by mass unless something else is specifically permitted. A ticket can satisfy that standard and still bill wrong, because what a contractor owes comes from the order and its price terms.

No two customers want quite the same ticket. Georgia's DOT requires its Form 525 with every load, showing project, date, time, class and quantity, actual batch proportions, free moisture in the aggregates, water withheld and mixing revolutions. Michigan's pavement concrete section wants ticket data computer generated, room for the inspector's signature, and an automated printout of target and actual batch weights tied to the ticket's serial number. Iowa's construction manual lets later trucks on continuous mainline paving carry only a few entries after a complete first ticket, but intermittent work such as bridge approaches needs the full form on every load. Commercial general contractors add their own job and PO demands on top.

Plant certification runs on a calendar. Wisconsin's state building master specification for site concrete names NRMCA's Certification of Ready Mixed Concrete Production Facilities as a manufacturer qualification. North Carolina's DOT goes further: a December 2025 letter tells producers that staying on its Approved Producers List takes an NRMCA plant inspection every two years and a delivery fleet inspection every year, with six signed documents emailed before the current certificate expires and no extensions granted. NRMCA puts typical processing of a correct checklist at two weeks and says it can reach four.

The mix file gets audited. That same North Carolina letter describes a state audit at least once per calendar year. Auditors verify that required documents are on site and current, look at bills of lading and mill certifications for stockpiled materials, and confirm that approved mix designs are in use and that their materials match the stockpiles. A changed cement or aggregate source that never reached the mix file is the kind of gap such an audit is built to find, which is why submittals and their backup deserve a careful desk.

Both jobs come with an answer key. Dispatch and batching happen live, minute by minute, and nothing here goes near them. Billing and QC work from finished paper. A billed ticket has the invoice your office sent, and a returned submittal has the engineer's marks. Those records let your reviewer compare each draft with what your team actually did, ticket by ticket or requirement by requirement.

One limit covers both. The proof of concept never touches your dispatch or batch system, your billing system or a live invoice, and it never approves a mix or signs a submittal. A person checks every invoice, and the engineer of record decides every submittal. Standards and agency rules are named here so you can recognize them; nothing on this page is legal or engineering advice.
